Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lengthening device for a press machine for knitted products for stretching the length of knitted products to finished dimensions.

[Conventional technology]

After knitted products are knitted, there is a process of shaping them into predetermined dimensions.

5 to 7 are diagrams showing the configuration of a conventionally used press machine for molding to the above-mentioned predetermined dimensions.

In this press machine (FIG. 5), a hollow body dummy 2, which is a press mold, is erected on a support stand 1. In addition, a large number of small ventilation holes are formed on the surface of the body dummy 2, and knit products are attached to the body dummy by a steam blow mechanism, a hot air blow mechanism, a vacuum mechanism, etc. provided inside the body dummy. On the other hand, steam, hot air blowing, vacuuming, etc. are carried out through the ventilation holes. Further, the body dummy 2 is divided into three parts in the width direction, and the width A can be increased or decreased by operating a width adjustment handle 3 provided on the support base 1.

When pressing, first, the width adjustment handle 3 is operated to adjust the width of the body dummy 2 to the finished width, and the knit product W is mounted on the body dummy 2. After this, steam blowing is performed to make the heated knit product W flexible, and the hem W ₁ is pulled down by hand to adjust the length to the finished dimensions.
Stop steam blowing.

Thereafter, the knitted product W is dried by hot air blowing and further cooled by a vacuum operation, thereby completing a series of pressing steps and molding the knitted product to a predetermined finished size.

By the way, in the above-mentioned pressing process, when the length of the knitted product W is lengthened, the knitted product W is heated to a considerably high temperature due to the steam. Therefore, it is dangerous to directly grasp the knitted product W with your hands during work, and moreover, only the part that is grasped stretches at the hem.
There was a problem in that it took time to spread W ₁ uniformly, and work efficiency was low. Therefore, conventionally, as shown in FIG. 7, in the sewing stage, two annular parts Wa, Wa called waste bags were formed at the lower end of the hem, and the rods 4, 4 were inserted into the waste bags Wa, Wa, respectively. ,
During the lengthening work, the worker held both ends of the rods 4, 4 and pulled down W ₁ along the guide columns 5, 5.

According to this, the danger is significantly reduced compared to the case where the product is directly grasped by hand, and since the entire hem is pushed down by the rods 4, 4, the length can be uniformly increased.

[Problem that the invention seeks to solve]

However, when lengthening using the rods 4, 4 as described above, the hem of the knitted product W
It is necessary to form waste bags Wa, Wa on W ₁ , which are not needed as a product, and after pressing, these bags are placed at the hem.
It was necessary to remove it from W ₁ , which increased the number of work steps and increased costs. Further, depending on the product, there are some products in which a waste bag WaWa cannot be formed, and in such a case, it is necessary to directly grasp the hem portion _W1 to lengthen the product.

This invention has been made by focusing on the above-mentioned problem, and is a lengthening device for a press machine for knitted products that can safely and easily adjust the length of any knitted product without performing any processing. The purpose is to provide.

[Means for solving problems]

This invention includes a locking means for locking the hem of a knitted product attached to a body dummy, and a holding member for holding the upper end of the knitted product, which is moved along the length direction of the knitted product after the steam spraying operation starts. It is equipped with a moving mechanism that moves it in a direction away from the hem.

[Effect]

In this invention, the knit product attached to the body dummy is first locked at the hem by the locking member, and held at the upper end by the holding member, and then by the steam discharged from the inside of the body dummy. It becomes flexible. In this state, the holding member moves in a direction away from the hem while holding the upper end of the knit product, thereby extending the length.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 2.
This will be explained based on the diagram. Note that the same or equivalent parts as in the conventional example are given the same reference numerals, and detailed explanation thereof will be omitted.

In the figure, reference numerals 6a and 6b are T-shaped mounting bases movably provided on both sides of the support base 1, and these mounting bases 6a and 6b are simultaneously raised and lowered by operating a handle 7. 8, 8, 9, 9 is this mounting base 6
Two sets of air cylinders are arranged facing each other on the upper surfaces of a and 6b, and by operating the pedal _P4 , cylinder rods 8a, 8a,
9a and 9a advance and retreat. Reference numerals 10 and 11 denote two locking plates held by the cylinder rods 8a and 9a, which are disposed opposite to each other at the front and rear of the body dummy 2, and the inner surfaces of the locking plates 10 and 11 are provided with Multiple locking needles are implanted. Note that the above 6 to 11 constitute the locking means A.

12 and 13 are support plates 6c installed on the support stand 1;
At 6d, air cylinders for lifting and lowering as a moving means are provided on both sides of the upper part of the body dummy, and are turned ON and OFF by operating the lengthening pedal _P5 , thereby raising and lowering the cylinder rods 12a and 13a. Reference numeral 14 denotes a lengthening rod as a holding member that is supported by hooks 12b and 13b provided at the upper ends of the cylinder rods 12a and 13a, and its tip end passes through the ∩-shaped bag-like stitch at the upper end of the knit product W. It has a sharp-edged shape that allows it to be used. In addition, P ₁ is the steam pedal for operating the steam blow mechanism, P ₂
is a hot air pedal for operating the hot air blow mechanism, and P ₃ is a vacuum pedal for operating the vacuum mechanism. Further, 15 is a power switch.

The operation will be explained based on the above configuration.

At the time of pressing, the handle 3 is first operated in the same manner as before to adjust the width of the body dummy 2 to the finished width, and the knitted product W is attached thereto. After this, operate the handle 7, adjust the height of the locking plates 10 and 11 to the hem W ₁ of the knit product W, and press the hem presser.
Depress _P4 to turn on cylinders 8, 8, 9, and 9, and project cylinder rods 8a, 8a, 9a, and 9a. As a result, both the locking plates 10 and 11 move toward the body dummy 2, and the knit product W is held between them and the body dummy 2. At this time, the locking needles embedded in the locking plates 10 and 11 penetrate the seams of the knitted product and are also inserted into the ventilation holes of the body dummy 2, so that the knitted product W held between them passes through the seams of the knitted product. The hem is securely locked.

After that, the lengthening rod 14 is passed through both sides of the upper end of the knitted product W, that is, both shoulders, and both ends of the rod 14 are attached to the hooks 12 and 13 of the lengthening cylinders 12 and 13.
b, 13b is held. In addition, the length rod 14
Because it penetrates the stitches of the knit product W, the product is not damaged, and even if the stitches at the penetration part are widened, this part is removed when forming the sleeve holes, so the product value is reduced. There is no risk of it being damaged.

Next, the steam pedal _P1 is depressed to blow steam, and the lengthening cylinders 12 and 13 are operated by the lengthening pedal _P5 to protrude the cylinder rods 12a and 13a, and the lengthening rod 14 is pushed upward. go. As a result, the knitted product W containing steam is stretched by the lengthening rod 14 and stretched to a predetermined finished size.

Note that the length at the time of finishing is usually reduced by about 5% before the finishing process, and the amount of elongation is set in advance by a setting means not shown.

After the lengthening operation, the hot air pedal P ₂ and vacuum pedal P ₃ are operated as appropriate, and the pressing operation is completed.

In this way, in the above embodiment, the worker does not have to touch the knitted product at all during the lengthening work, so safety is greatly improved. Because it is stretched, uniform length can be achieved.
